Smeltery

Overview
The Smeltery is an upgraded crafting station from the Forge. Unlike its predecessor, the Smeltery is capable of creating Mithril and Bluesteel tools.

It is notably larger than the Forge, containing a larger anvil and a much larger furnace for smelting ores, hence the name. If a tribe happens to have one, then they are likely armed with end-game weapons, making it unwise to attack them unless you have the same.
